Why Driverless Trucks Will Cruise the Slow Lane

News reports tell us driverless cars are on the brink of ubiquity. This would soon mean driverless trucks could become commonplace, resulting in millions of truck drivers being replaced by robots. Very credible, unless you think about it for, say, more than 30 seconds. Maybe it's just me and my heartbreaking experience at the New York World's Fair in 1964, where I saw robots in the kitchen, video telephones and yes, driverless cars that also flew. We were promised that they would be here soon.
